Monal

Monal is an XMPP instant messaging client for macOS. XMPP is an open, standardized protocol for real-time communication; accounts use addresses in the form [email protected], and the network can connect people using different apps and services. This Homebrew entry installs the beta macOS app, not the iOS version.

• Provides XMPP chat on macOS.
• Works with XMPP accounts, which can be used across different apps and services.
• Monal is also available for iOS, but that version is not installed by this cask.

Install the beta variant with brew install --cask monal@beta, then open Monal from Applications. The beta cask conflicts with the separate monal cask, so they cannot be installed together. The cask is marked as requiring macOS; no specific minimum version is provided.
